Abstract
Improved capillary zone electrophoresis (CZE), affinity capillary electrophoresis (ACE), and partially filled-ACE (PF-ACE) systems and methods for the detection and quantification of specific molecular entities in a mixture thereof are provided. During manufacturing, heterodimeric bispecific antibodies are often produced along with homodimer species, which can confound quantification of the bispecific antibody. Disclosed are capillary electrophoretic systems and methods of detecting a specific homodimer in the mixture of bispecific heterodimer and homodimers. A ligand capable of binding one of the subunits of the bispecific antibody is contacted with the mixture to form a complex having a reduced electrophoretic mobility, thereby enabling detection of the unbound homodimer.
